In one embodiment, a vehicle-mounted display control method is provided and applied to the vehicle-mounted display. The vehicle-mounted display comprises a vehicle-mounted information processing controller, a display panel and a touch strip, wherein the vehicle-mounted information processing controller is respectively connected with the display panel and the touch strip, and the touch strip and the display panel are arranged at an angle.
In practical applications, the touch panel is disposed opposite to the display panel. The display content of the display panel can be reflected to human eyes through the touch panel. And the user performs touch operation at the corresponding position of the display content, namely performs touch operation at the corresponding position on the touch panel, so that the touch panel generates a touch signal and transmits the touch signal to the vehicle-mounted information processing controller. The touch operation on the user touch panel is limited to the display content of the display panel.
And the vehicle-mounted display has hundreds of virtual keys, cannot be concentrated on one display page and can only be distributed on different pages. Clicking a virtual key may require page switching for multiple times to reach the page, which is tedious in operation and may affect driving safety.
However, for the touch bar, the touch bar is disposed at an angle to the display panel, such as 90 °, that is, the touch bar is perpendicular to the display panel. The touch operation of the user on the touch bar is not limited by the display content of the display panel. No matter what the display content of the display panel is, a user can directly perform touch operation on the touch strip, so that the touch strip generates a touch signal and transmits the touch signal to the vehicle-mounted information processing controller.
As shown in fig. 4, the control method includes:
step S402, detecting touch operation by a touch bar on the vehicle-mounted display.
The touch operation comprises at least one of single-finger sliding, double-finger sliding, multi-finger sliding, palm sliding, single clicking, double clicking, multi-tapping and long pressing.
Specifically, a finger of a user performs touch operation on a touch strip, a capacitance is formed between the finger and the touch strip by using a human body current induction phenomenon, a small current is absorbed when the finger touches the touch strip, and the current flows on the touch strip, so that the touch operation is detected.
As shown in fig. 5, the touch panel 30 is disposed on the front surface of the in-vehicle display 100, the touch bar 40 is disposed on the side surface of the in-vehicle display 100, and the touch panel 30 is perpendicular to the touch bar 40. The display panel 50 is also disposed on the front surface of the in-vehicle display 100, opposite to the touch panel 30. The user's finger performs a touch operation on the touch bar 40, the touch bar 40 generates a touch signal and transmits the touch signal to the in-vehicle information processing controller 60, and the in-vehicle information processing controller 60 controls the display content of the display panel 50.
Step S404, when the touch bar detects a target touch operation, generating a corresponding target touch signal based on the target touch operation, and transmitting the target touch signal to the in-vehicle information processing controller.
The target touch operation is a touch operation detected by the touch strip. The target touch signal is a touch signal generated by the touch bar when the touch operation is detected. For example, a single-finger slide is performed on the touch strip, the target touch operation is a single-finger slide, and the target touch signal is a touch signal generated by the touch strip in a single-finger slide area.
It should be noted that the touch signal generated by the touch bar is an edge touch signal, which is different from the touch signal generated by the touch panel on the vehicle-mounted display.
Specifically, a finger of a user performs touch operation on the touch strip, a capacitance is formed between the finger and the touch strip by using a human body current induction phenomenon, and a small current is absorbed when the finger touches the touch strip, so that the current flows on the touch strip. This current signal is the touch signal. When a user performs touch operations at different positions on the touch strip, different touch signals are generated.
In step S406, the in-vehicle information processing controller determines a corresponding target touch operation based on the target touch signal, and generates a target control instruction corresponding to the target touch operation.
The target control instruction is used for controlling and executing corresponding target operation, and the target operation is the purpose of target touch operation. For example, in order to increase the volume, the target touch operation is a single-finger slide on the touch bar, the target operation is to increase the volume, and the target control instruction is to control the volume to be increased.
Specifically, a user performs a touch operation at different positions on the touch strip, and different touch signals are generated. The received touch signal is identified, and the touch operation of the user can be determined. For example, the touch position of the user changes in a certain direction, possibly sliding. As another example, the user's touch location does not change but has an interruption, perhaps a tap.
The touch operation corresponds to the control instruction one by one. For example, a single-finger slide corresponds to volume adjustment, a single-finger double-click slide corresponds to brightness adjustment, and a double-finger slide corresponds to application interface switching. The corresponding relation between the touch operation and the control instruction can be established in advance and stored in the memory. And when the vehicle-mounted information processing controller receives the target touch signal, determining corresponding target touch operation, acquiring the corresponding relation from the memory according to the target touch operation, and searching a control instruction corresponding to the target touch operation.
In step S408, the in-vehicle information processing controller controls to execute a target operation corresponding to the target control instruction, and sends the target control instruction to the display panel to control the display panel to display an operation content corresponding to the target operation.
The target operation is volume adjustment, brightness adjustment, application page switching and the like. The operation content is a result after the target operation is executed. Such as adjusted volume value, adjusted brightness value, switched page, etc.
Specifically, the vehicle-mounted information processing controller controls and executes target operation corresponding to the target control instruction, and meanwhile, the target control instruction is sent to the display panel, and the display panel displays the execution result of the target operation. For example, if the target control command is to increase the volume, the in-vehicle information processing controller controls the volume to be increased, and the display panel displays the increased volume value (as shown in fig. 6). In another example, if the target control command is to decrease the brightness, the in-vehicle information processing controller controls the decrease of the brightness, and the display panel displays the decreased brightness value (as shown in fig. 7). If the target control instruction is to switch the application interface, the in-vehicle information processing controller controls the switching of the page, and the display panel displays the switched application page (as shown in fig. 8).
The vehicle-mounted display control method is applied to a vehicle-mounted display, the vehicle-mounted display comprises a vehicle-mounted information processing controller, a display panel and a touch strip, the vehicle-mounted information processing controller is respectively connected with the display panel and the touch strip, touch operation is carried out on the touch strip, and the touch strip can generate a touch signal and transmit the touch signal to the vehicle-mounted information processing controller to control the display content of the control panel. The touch bar and the display panel are arranged at an angle, and the touch operation on the touch bar is not limited by the display content of the display panel. During specific implementation, a touch control bar on the vehicle-mounted display detects touch control operation, generates a corresponding target touch control signal based on the target touch control operation when the target touch control operation is detected, and transmits the target touch control signal to the vehicle-mounted information processing controller. In this way, the on-board information processing controller can determine a corresponding target touch operation based on the target touch signal and generate a target control instruction corresponding to the target touch operation, so that the on-board information processing controller controls and executes the target operation corresponding to the target execution instruction and sends the target control instruction to the display panel to control the display panel to display the operation content corresponding to the target operation. The whole process can be separated from the limitation of the display content of the display panel, the corresponding control page can be reached without carrying out page switching for many times, the operation is simplified by utilizing edge touch, the vehicle-mounted equipment is directly and efficiently controlled, the adverse effect on the driving safety is effectively avoided, and the display device is particularly suitable for being mounted on the vehicle-mounted display of a vehicle cabin.
